摘　　要：通过对磷酸钾镁水泥(MKPC)砂浆流动度、强度变化、体积变形、水稳定性和微观分析,研究了骨料种类和胶砂比对大流动性MKPC砂浆物理力学性能及微观结构的影响。试验结果表明,相同胶砂比下,采用石英砂能获得更好的抗压强度、流动度及体积稳定性,胶砂比越大,硬化体力学性能越好。Through the analysis on the fluidity,strength change,volume deformation,water stability and microcosmic of potassium magnesium phosphate cement(MKPC)mortar,researched the influence of aggregate type and mortar ratio on the physical and mechanical properties and microcosmic of MKPC mortar with high fluidity.The test results showed that under the same cement sand ratio,quartz sand could obtain better compressive strength,fluidity and volume stability,the larger cement sand ratio,the better mechanical properties of hardened body.
